[origin: EP0817224A1] At the first level, in the compartment (34) near the contacts (17, 18), the arc is laminated at the beginning of the opening of the moving contact (17) so as turn the arc by upper and lower arc guide horns (28, 30) extending into the second compartment (36). The half-shells have a section standing proud in the second compartment to form a transverse zig-zag between the guides. The extinction chamber (22) is in the third compartment (38) with a first series of decompression holes (44) made in the shells in the neighbourhood of a step with a chamfered edge (48) separating the second and third compartments and opening out before the holes. A gas exit hole (54) lies at the top of the third compartment.
